Dear Colleague,

Lipid emulsion was initially developed for parenteral nutrition. Lipid emulsion has been widely used for the treatment of local anesthetic systemic toxicity. In addition, these days, lipid emulsion was reported to be effective in alleviating toxicity of nonlocal anesthetic drugs with high lipid solubility. Although lipid emulsion is used to treat intractable cardiovascular collapse induced by toxicity of nonlocal anesthetic drugs (amitriptyline, bupropion, quetiapine, verapamil, and diphenhydramine) with high lipid solubility, many physicians have a tendency to consider only the lipid sink as the underlying mechanism, in which the lipid emulsion absorbs highly lipid soluble drugs from vital organs, leading to a reduction in the offending drug content in vital organs such as the heart. However, many mechanisms other than the lipid sink have been demonstrated to be involved experimentally, including lipid shuttle (enhanced redistribution), inotropic effects, inhibition of nitric oxide production, fatty acid supply, attenuation of mitochondrial dysfunction, and glycogen synthase kinase-3b phosphorylation. For this Special Issue, we welcome all research papers associated with lipid emulsion treatment of systemic toxicity induced by local anesthetics or nonlocal anesthetic drugs, including antidepressants, antipsychotics, calcium channel blockers, and anti-arrhythmic. Such a collection would be helpful in providing insights toward improving lipid emulsion treatment of toxicity caused by local anesthetic or nonlocal anesthetic drugs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
